REALLY??? So do you not know what a radio button is or do you not
know what happens when you select one?
OK, here is the explanation of radio buttons. Radio buttons are used
for single-choice lists (and spinners and AlertDialogs and, well,
Radio Button groups). In every case, each item in the set of
selectable items has a graphic element that is designed to look like a
button with a green light in the center that can either be lit up or
not, simulating car radios of a certain era. Only one of the items in
a group of radio button-equipped items can be selected at a time,
hence the term single-choice, unlike a multi-choice set which employs
check box graphics. The radio button on an item lights up when you
select the item and at the same time the light of the previously-
selected button goes out.
I was under the impression that almost every programmer with any UI
experience was familiar with this paradigm but maybe not. Even if
not, I feel confident that almost anyone one who has ever created a
single-choice ListView (i.e. one with radio buttons) knew what I was
asking and they were the target audience for my question. While I
admit that I do not know the actual percentage of people on the list
who have ever created a single-choice ListView or who are at least
familiar with the concept and the API, I am pretty sure that the
number must be significantly larger than the number who bothered to
answer my question (zero).
